Pros
Pro Very good entity system, did have GUI functions, easy to use terrain editor with vegetation system.
Good API tutoials, workshop elements which can be loaded from steam.
Pro Both Windows and Linux supported
Pro Built-in level editor
Has an acceptable 3D map editor that is easy to use.
Pro Versatile flow diagram script model
Leadwerks's flowgraphs resemble flowcharts where each box represents a function or value, with connections between them representing program flow. This provides a better at-a-glance indication of game logic than a simple list of events, and makes complex behaviors easier to accomplish.
Pro Community forum offers plenty of support
It makes game developing much easier if you have someone backing you up when you run into a bug or other issues, and get replies within hours .
Pro Decently sized library of tutorials for both Lua and C++
Pro Very clean and easy C++ API
Pro Lua scripting support
Pro Reasonably priced
Standard edition of Leadwerks costs 92,99€. Additionally, it often goes on sale on Steam.
Pro C++ scripting support
Pro Terrain editor
The terrain editor allows sculpting, paint, vegetation placement and importing of external maps. Especially the painting is done very well and can lead quickly to very professional looking results.
Pro Easy to use API and scripting language
Pro Easy to use
You'll need to put more time in learning Unity + Playmaker compared to something like GameSalad. But once get the hang of it and familiarize yourself with what it's possible to build with them, it's quite easy to use.
Pro Provides access to a huge list of assets through Asset Store
For those developers who can't afford an artist, or aren't skilled enough to create their own art, Unity features an Asset Store full of a wide variety of free and paid assets that can be easily added to your game. The Asset Store has more than just music and art. It also has code and modules that can be added to your game such as unique lighting or GUI systems.
Pro Third party plugins support
A lot of third party plugins have support for Playmaker. Playmaker team also invest time to add support for a lot of third party plugins.
Pro Elegant state-based visual scripting
Instead of a single "if this then that" event list which can become very cluttered beyond the most basic behaviors, PlayMaker gives each object a list of states where only certain events are triggered, and performing an action also changes state.
This allows for a clean, simple visual representation which helps break complex logical structures into smaller pieces, making them easier to understand.
Pro Powerful
It basically can do same things as scripting in Unity.
Cons
Con Little to no support
This product relies on community support, although some members are helpful and quite approachable they don't like to share their secrets with people that are new to programming.
The product is sold as a Full featured platform but it seems to more in the Alpha stage of development as a lot of the good aspects where taken out in previous versions.
Con Has a track record of broken promises
Con Forums are poorly run and censored
Con Highly misleading advertising
Con Only prefabs made with the Leadwerks IDE could be used.
The two main problems for me is that C++ is not as easy to use like LUA. The IDE should also support C++. The secons is that only prefabs can be used which are made with the IDE. So you can not easy made a game that can be modded by the user.
Con Weak out-of-the-box AI
The only AI movement function is going in a straight line.
Con Very buggy
Leadworks is a not complete, it's a work in progress. As such many parts of the engine are clunky, especially the level editor.
Con Comparatively high learning curve
Although C#, JavaScript, and Boo have extensive documentation available online, it could still be difficult to wrap your head around the library and Unity's component based system.
Con Limited tutorials
There are not a lot videos with Playmaker tutorials. Official text tutorials are also quite limited. Even not every action has a description on an official wiki.
Con Performance could be better for 2D
Performance can be a real issue with 2D games. Unity 3D is actually a 3D game engine, and drags a lot of overhead with it.
For mobile, one could never achieve the performance of more specialized 2D engines with Unity3D.
